Contractors and DIYers, this IVY Classic masonry wheel is exactly what you need for grinding through tough materials. This 7-inch depressed center wheel is built with resin-bonded silicon carbide that chews through brick, concrete, tile, slate, and pretty much any masonry material you throw at it. The double reinforced fiberglass mesh makes it super durable and safe - no worrying about it shattering during use. It's got a metal-reinforced arbor (that's 5/8-inch with 11 threads) for extra strength when you're really putting pressure on it. Max RPM is 8,600 so it works with most standard angle grinders. What I love about this wheel is how consistent it grinds - no skipping or uneven wear. It's a Type 27 blade specifically for grinding, not cutting, so it's perfect for smoothing rough concrete surfaces, removing mortar, or shaping stone work. Whether you're a professional contractor working on job sites or a homeowner tackling a backyard project, this wheel gets the job done without burning out too quickly. Seriously reliable performance that won't let you down when you're in the middle of a big project.
